The Six Healing Sounds or Liu Zi Jue (六字訣) is one of the common forms of Chinese qigong, and involves the coordination of movement and breathing patterns with specific sounds.

The Term Liu Zi Jue first appears in a book called On Caring for the Health of the Mind and Prolonging the Life Span written by Tao Hongjing of the Southern and Northern Dynasties (420 - 589). A leading figure of the Maoshan School of Taoism, Tao was renowned for his profound knowledge of Traditional Chinese Medicine. "One has only one way for inhalation but six for exhalation" he writes in the book.

Zou Pu'an of the Song Dynasty (960 - 1279) was a major contributor in terms of theory and practice to the transmission of the exercise through his book The Supreme Knack for Health Preservation - Six-Character Approach to Breathing Exercises.

No body movements accompanied the Liu Zi Jue exercises until the Ming Dynasty (1386 - 1644) when Hu Wenhuan and Gao Lian wrote books on the subject. For instance they both included in their books the summary of Liu Zi Jue for despelling diseases and prolonging the life span, which combines controlled breathing with physical exercises.

Liu Zi (劉滋) (729 – November 19, 794), courtesy name Gongmao (公茂), was an official of the Chinese dynasty Tang Dynasty, briefly serving as a chancellor during the reign of Emperor Dezong.

Liu Zi was born in 729, during the reign of Emperor Xuanzong. His family traced its ancestry to the imperial house of Han Dynasty and a line of officials of the Jin Dynasty (265-420), Northern Wei, Northern Qi, Sui Dynasty, and Tang Dynasty. Liu Zi's grandfather Liu Zixuan was a prominent official and historian during Emperor Xuanzong's reign, and his father Liu Kuang (劉貺) continued in the role of historian thereafter.

Les Six is a name, inspired by Mily Balakirev's The Five, given in 1920 by critic Henri Collet in an article titled "Les cinq Russes, les six Français et M. Satie" (Comoedia, 16 January 1920) to a group of six composers working in Montparnasse. Their music is often seen as a reaction against the musical style of Richard Wagner and the impressionist music of Claude Debussy and Maurice Ravel.

Formally, the Groupe des Six members were:

In 1917, when many theatres and concert halls were closed because of World War I, Blaise Cendrars and the painter Moise Kisling decided to put on concerts at 6 Rue Huyghens, the studio of the painter Émile Lejeune. For the first of these events, the walls of the studio were decorated with canvases by Picasso, Matisse, Léger, Modigliani and others. Music by Erik Satie, Honegger, Auric and Durey was played. It was this concert that gave Satie the idea of assembling a group of composers^[which?] around himself to be known as Les nouveaux jeunes, forerunners of Les Six.
